Abstract
Taking into account the gluon correction contributions to the correlation function, the form factors relevant to the rate B-c --> X nu(nu) over bar decays are calculated in the frame-work of the three-point QCD sum rules, where X stands for axial vector particle, AV(D-s1), and vector particles, V(D*, D-s*). The total decay width as well as the branching ratio of these decays are evaluated using the q(2) dependent expressions of the form factors. A comparison of our results with the predictions of the relativistic constituent quark model is presented.
